In at least one embodiment, the composition or therapeutic composition includes one or more frozen solution particles and the composition or therapeutic composition is in at least one crystalline or amorphous phase. In at least one embodiment, the frozen solution particles include at least one of the constituents described herein.

In at least one embodiment, the one or more frozen particles include frozen hydrogen oxide particles. Frozen hydrogen oxide, or typical water ice, exists in several non-crystalline forms.

Hydrogen oxide (water) has many frozen phases (ices), including crystalline and non-crystalline phases. The crystalline phases generally have the common structure of having hydrogen bonds to four neighboring water molecules, such as two hydrogen atoms near each oxygen atom. Structural data on the known frozen hydrogen oxide polymorphs are shown in Table I, with two known phases of ice XI. (See, e.g., Chaplin, Ibid; and Zheligovskaya, et al., Russian Chem.

Cooling liquid hydrogen oxide below its standard freezing point typically results in the formation of frozen hexagonal ice. However, if the hydrogen oxide is pure and cooled slowly, the liquid hydrogen oxide can be supercooled to approximately −42° C. Amorphous solids harden without crystallizing, such that if hydrogen oxide is cooled rapidly it results in formation of a glass-like state, for example, hyperquenched glassy water. (See e.g., Debenedetti, J. Phys. Condens. Matter, vol. 15, pp. R1669-R1726 (2003), and as cited by Chaplin, worldwideweb at lsbu.ac.uk/water; each of which is incorporated herein by reference.) Generally, hyperquenched glassy water is formed by rapidly spraying a fine mist of micrometer-sized hydrogen oxide droplets into very cold liquefied gas, such as propane. Alternatively, a fine mist of hydrogen oxide can be sprayed onto a very cold frozen substrate, at or below approximately −193° C. Hyperquenched glassy water may also be formed by cooling capillary tubes containing bulk liquid water (−100 μm diameter) with liquid helium at approximately −269° C.

As shown in FIGS. 1-4, hydrogen oxide attains various structures and phases depending upon the temperature or pressure of the environment. As indicated in FIG. 1, for example, hydrogen oxide ice Ic is derived from high density amorphous water or deeply supercooled liquid water, when put under low temperature or higher pressure. Likewise, as indicated in FIG. 2, the hydrogen oxide has a greater density as a liquid than as a solid under ambient conditions (ice Ih). However, at increasing pressure, at least ice stages III, V, VI, and VII exhibit a greater density than liquid hydrogen oxide. FIG. 3 indicates the phase diagram for hydrogen oxide based on pressure and temperature variance, while FIG. 4 shows the specific sub-categories of hydrogen oxide based on physical properties, such as structure and density, among others, as the temperature and pressure vary.

Similarly, amorphous solid water is formed from the slow deposition of hydrogen oxide vapor on a cold metal crystal surface (at less than approximately 2 nm/s), below the temperature of approximately −153° C. Amorphous solid water is a viscous semi-solid material that has a density of approximately 0.94 g/cm³ and harbors gaps and spaces in its structure, as well as reactive hydrogen bonds. These structures are removed by annealing under vacuum pressure, which allows the material to convert to a high density glassy water or low density amorphous ice, depending on the temperature. Typically, high density glassy water, which has a density of approximately 1.1 g/cm³, is formed by vapor deposition at approximately −263° C.

Low-density amorphous (LDA) ice also occurs from heating high-density amorphous (HDA) ice to just above approximately −153° C. at atmospheric pressure, and transforms to cubic ice at approximately −113° C. to −123° C. Low-density amorphous ice is also prepared by submitting low-pressure phases (Ih, Ic, XI, etc.) to high pressure (approximately 1.0 GPa) at low temperatures (e.g., below approximately −148° C.).

Very-high density amorphous (VHDA) ice is a viscous water state with a density of approximately 1.25 g/cm³, and is prepared by heating high-density amorphous ice to just above approximately −113° C. and approximately 1.15 GPa. When very-high density amorphous ice is heated at different pressures between 0.3 and 2 GPa, it re-crystallizes into only the proton disordered ices III, IV, V, XII, VI and VII in order of increasing pressure, but does not typically re-crystallize into the proton ordered phases (e.g., ice II).

Typically, the density of liquid water increases with increased pressure. When liquid water approaches the critical point in the liquid-vapor phase, water enters a supercritical phase where it exists as small but liquid-like hydrogen-bonded clusters dispersed within a gas-like phase and its physical properties vary according to changing density. Supercritical water is an excellent solvent for non-polar molecules, due to its low dielectric constant and poor hydrogen bonding. Due to these same properties, supercritical water is typically not a good solvent for electrolytes, which tend to form ionic bonds.

As indicated in FIG. 2, hexagonal ice is less dense than liquid water, whereas the other ice phases are all denser and phase changes occur near the liquid and solid densities (See e.g., Loerting et al., J. Phys.: Condens. Matter vol. 18, R919-R977 (2006), which is incorporated herein by reference). Liquid water density varies with change in temperature or pressure, whereas the density of amorphous ice varies only with change in pressure, but not temperature.

Hydrogen oxide has a high heat of vaporization (approximately 40.7 kJ/mol), and a high heat of sublimation (approximately 51.059 kJ/mol at 0° C.), which allows for the frozen particles to remain intact for a short time period during which the particles are delivered to one or more cells or tissues. These properties further enable the frozen particles to serve as particles for delivery of at least one therapeutic composition to one or more cells or tissues.

Hydrogen oxide becomes more viscous as the temperature is decreased to below approximately 33° C., or the pressure is increased. Frozen particles may include a “solid,” such as true solids, semi-solids, and viscous fluid, such as gels, hydrogels, or sols. Frozen particles may include particles that are at least partially frozen, or are entirely frozen. Compositions including one or more particles may include one or more subset groups of one or more particles, some of which may be entirely frozen and some of which may be at least partially frozen. Such compositions may include multiple different compositions, where the group of frozen particles includes at least one subset that includes multiple particles, wherein each particle has an individual therapeutic agent or unique composition. The group of frozen particles may also include at least one subset of multiple particles, wherein each particle includes multiple agents (including therapeutic agents).

A particular plurality of compositions or therapeutic compositions may include multiple frozen particles where various multiple agents are associated with a single particle. Likewise, a particular plurality of compositions or therapeutic compositions may include various multiple agents, where each individual agent is associated with a single frozen particle. In at least one embodiment, a plurality of compositions or therapeutic compositions may include any number of subsets of frozen particles associated with a particular therapeutic agent or other constituent. During the course of any particular method described herein, one or more plurality of compositions or therapeutic compositions, or any particular subset thereof, may be administered in a single treatment.

In at least one embodiment, the one or more frozen particles exist at about 30° C., about 20° C., about 10° C., about 5° C., about 0° C., about −10° C. about −20° C., about −30° C., about −40° C., about −50° C., about −60° C., about −70° C., about −75° C., about −80° C., about −85° C., about −90° C., about −95° C., about −100° C., about −120° C., about −150° C., about −180° C., about −200° C., about −220° C., about −250° C., or any value less than or therebetween.

In certain instances, the one or more frozen particles are utilized at a very cold temperature so that effective penetration of a biological tissue is achieved. In certain instances, the one or more frozen particles are utilized at warmer temperatures, particularly if the contents of the one or more frozen particles include agents that have warmer freezing temperatures. For example, the freezing point of nitrogen is approximately −210° C., whereas the freezing point of dimethyl sulfoxide (DMSO) is approximately 18.45° C. Thus, frozen particles of DMSO can be utilized or administered at a warmer temperature than can frozen particles of nitrogen.

Ice Ic is generally formed by condensation of water vapor, at ambient pressure and low temperatures (less than approximately −80° C.), or below approximately −38° C. as a mist. (See e.g., Murray et al., Phys. Chem. Chem. Phys. Vol. 8, pp. 186-192 (2006), which is incorporated herein by reference). Ice Ic is also prepared by reducing the pressure on high-pressure hydrogen oxide ice at approximately −196° C. It may be the preferred phase for ice formed from hydrogen oxide droplets smaller than about 15 nm in radius, particularly at low temperatures (e.g., −113° C. to −53° C.). (See e.g., Johari, J. Chem. Phys. vol. 122 pp. 194504 (2005); Zhang, et al., Chem. Phys. Lett. vol. 421, pp. 251-255 (2006), each of which is incorporated herein by reference).

Ice Ih constitutes a large portion of naturally-occurring snow and ice. Since hexagonal ice exhibits changes in the hydrogen bonding, ice Ih shows anomalous reduction in thermal conductivity with increasing pressure (as does cubic ice and low-density amorphous ice). (See e.g., Andersson et al., Phys. Rev. B vol. 65 pp. 140201.1-14201.4 (2002), which is incorporated herein by reference).

Ice II maintains a general rhombohedral unit shape, similar to ice I. The density of ice II is approximately 1.17 g/cm³. Ice III maintains a general tetragonal unit shape, with a density of approximately 1.14 g/cm³. Ice VI also maintains a general tetragonal unit shape, with a density of approximately 1.31 g/cm³. Ice VII is primarily composed of multiple intercalating ice Ic lattices, and has a density of approximately 1.66 g/cm³.

In at least one embodiment, the therapeutic composition includes at least one of a solid, liquid, or gas. In at least one embodiment, the therapeutic composition includes one or more of a suspension, mixture, solution, sol, clathrate, colloid, emulsion, microemulsion, aerosol, ointment, capsule, powder, tablet, suppository, cream, device, paste, liniment, lotion, ampule, elixir, spray, suspension, syrup, tincture, detection material, polymer, biopolymer, buffer, adjuvant, diluent, lubricant, disintegration agent, suspending agent, solvent, colorimetric agent, light-emitting agent, glidant, anti-adherent, anti-static agent, surfactant, plasticizer, emulsifying agent, flavor, gum, sweetener, coating, binder, filler, compression aid, encapsulation aid, preservative, granulation agent, spheronization agent, stabilizer, adhesive, pigment, sorbent, nanoparticle, or gel.

In at least one embodiment, the at least one adhesive is included in one or more frozen particles. In at least one embodiment, the one or more frozen particles provide a vehicle for the at least one adhesive.

In at least one embodiment, at least one scaffold (e.g., collagen, elastin, protein, carbohydrate, nucleic acid, organic chemical, or other component) is provided with the at least one composition or therapeutic composition for one or more cells. In at least one embodiment, the scaffold provides a matrix for one or more cells. In at least one embodiment, the one or more cells are located in at least one biological tissue.

In at least one embodiment, clathrate compositions are included. Clathrate ice forms from water or other liquids, and contains small amounts of non-polar molecules (generally gases) under moderate pressure of a few MPa, and temperatures close to 0° C. Clathrate structures can vary, but generally allow a minimum amount of small molecules to fit into and stabilize gaps without forming covalent or hydrogen bonds with the hydrogen oxide molecules. Certain clathrates are formed at the interface of the liquid phase, under atmospheric pressure. Clathrates include but are not limited to the structural forms of sI, sII, and sh. In certain instances, noble gases may be used to form clathrate compounds with hydrogen oxide or other molecules. Noble gases generally have low polarizability, and tend to be spherically symmetrical, which allows for solubility with the hydrogen oxide cage. In addition, the solubility of the noble gases increases considerably as the temperature is lowered. The solubility of particular noble gases as clathrates with hydrogen oxide are shown in Table II. (See e.g., Dec et al., J. Solution Chem. vol. 14, pp. 417-429 (1985); Ivanov, et al., J. Struct. Chem. vol. 46, pp. 253-263 (2005); Fernandez-Prini, et al., Elsvier, pp. 73-98 (2004); Ivanov, et al., Russian J. Gen. Chem. vol. 75, pp. 1851-1856 (2005), each of which is incorporated herein by reference.)

In at least one embodiment, one or more subsets of frozen particles are delivered or administered according to a course of treatment (e.g., at least one subset of relatively small frozen particles are administered first, followed by at least one subset of relatively larger frozen particles; at least one subset of frozen particles are administered in a relatively fast velocity, followed by at least one subset of frozen particles administered by a relatively slow velocity; at least one subset of frozen particles approximately shaped as spheroids are administered followed by at least one subset of frozen particles approximately shaped as bullets, etc.).

In at least one embodiment, one or more methods described herein include delivering or administering one or more frozen particles by high velocity impact. In at least one embodiment, the one or more devices that utilize high velocity impact delivery provide at least one of localized delivery, targeted delivery, sustained delivery, modulated delivery, feedback controlled delivery. In some instances, an example of a device that may be used for administering one or more of the compositions described herein includes a handheld device, such as a wand, a pen, a baton, a hose, a sprayer, a gun (e.g., a pellet gun), or other handheld device. In certain instances, the device is at least part of a built-in delivery device, such as may be included in a wall, an overhead device, a corral, a gate, or a device that includes a cavity into which a subject may be placed for administration or delivery of at least one composition described herein. In certain instances, the device has robotic action. In any of these instances, the device may be remotely controlled, for example, by a human or computer program.

In at least one embodiment, delivering the at least one composition, including at least one therapeutic composition, to at least one biological tissue includes at least one of accelerating, ejecting, or propelling, the composition or therapeutic composition toward the at least one biological tissue. In at least one embodiment, the at least one composition is accelerated, ejected, or propelled to or at a predetermined pressure or velocity for delivery of the at least one composition to a desired location on or in the at least one biological tissue. In certain instances, the at least one composition or therapeutic composition is accelerated, ejected, or propelled at a particular pressure or velocity. In certain instances, the at least one composition or therapeutic composition is accelerated, ejected, or propelled at a predetermined pressure or velocity.

The velocity or pressure determined for delivery of the at least one composition to at least one biological tissue depends on certain factors, including but not limited to, size and density of the particle, content of the particle, desired effect or outcome of administration of the particle, density of the target tissue, density of surrounding tissue, type of tissue, architecture of the tissue, and other factors. In certain instances, the desired velocity or pressure for accelerating, ejecting, or propelling the at least one composition described herein will be the minimum velocity or pressure needed to achieve desired penetration of the tissue with the composition, whether for surface abrasion, therapeutic delivery, or other goal.

The means for accelerating, ejecting, or propelling the compositions described herein are non-limiting, and may include general methods for making, formulating, and delivering to at least one biological tissue by carrier gas under pressure, mechanical or electrical impulse assistance, centripetal or centrifugal force, or others, some of which are described herein. (See e.g., U.S. Pat. No. 4,945,050 and PCT application WO 92/01802, each of which is incorporated herein by reference). In certain instances, the one or more frozen particles are made, propelled, accelerated, or ejected simultaneously. Thus, the frozen particles may be made while propelled, the frozen particles may be made while accelerated, the frozen particles may be made while ejected, or any combination thereof.

In at least one embodiment, the one or more frozen particles are delivered or administered by a piezoelectric-type apparatus or device, by ultrasound-mediated transdermal drug transport, or by other device. When a voltage is applied, a piezoelectric-type apparatus generates a pressure pulse by change in shape or size of a chamber containing a fluid (or solid), and the pressure pulse drives the contents from the chamber. In one particular instance, a high velocity device (such as a powderject, air guns, or slingshot type devices) is utilized for injection of particles formulated with at least one therapeutic agent, for example, for therapy or prevention of a disease or condition.

For example, a powderject system, as described by Kumar and Philip (Trop. J. Pharm. Res., vol. 6, No. 1, pp. 633-644 (2007), which is incorporated herein by reference) propels frozen drug particles into the skin by means of high-speed gas flow (such as helium) that is usually painless and causes minimal bleeding or damage to the skin. (See also e.g., Tang et al., Pharm. Res., vol. 19, pp. 1160-69 (2002), which is incorporated herein by reference). As described by Kumar and Philip, particles contained in a cassette between two polycarbonate membranes located at the end of a chamber (Trop. J. Pharm. Res., vol. 6, No. 1, pp. 633-644 (2007), which is incorporated herein by reference). As described by Kumar and Philip, the polycarbonate membranes are ruptured when a carrier gas enters the chamber under high pressure, and the rapid expansion of the gas forms a shock wave that travels down the nozzle at a speed of approximately 600-900 m/s. Kumar and Philip report drug particle velocities of up to about 800 m/s at the nozzle exit, and the momentum density of the particles within the gas flow can be optimized for desired depth of penetration upon delivery to a biological tissue. (Trop. J. Pharm. Res., vol. 6, No. 1, pp. 633-644 (2007), which is incorporated herein by reference). In the powderject system, particle velocity is controlled by nozzle geometry, membrane burst strength, and gas pressure. (See e.g., U.S. Pat. Nos. 5,630,796; and 5,699,880, which are incorporated herein by reference).

Metered-dose transdermal sprays may also be used for delivery of at least one therapeutic composition as described herein. As described by Rathbone, et al., in one particular example, a topical solution containing a volatile then nonvolatile vehicle including a therapeutic agent is administered as a single-phase solution. (See Rathbone, et al., Modified Release of Drug Delivery Technology, N.Y., Marcel Dekker, Inc. vol. 126, pp. 471-619 (2004), which is incorporated herein by reference). A finite metered-dose application of the formulation to intact skin results in evaporation of the volatile component, leaving the remaining nonvolatile penetration enhancer or therapeutic agent to partition into the stratum corneum and creating a reservoir of the therapeutic agent(s). (See Rathbone, Ibid; and Kumar, et al., Trop. J. Pharm. Res., vol. 6, pp. 633-644 (2007), each of which is incorporated herein by reference).

In addition to these particular examples of devices that can be utilized for administration of the therapeutic compositions described herein, the therapeutic compositions can be administered in conjunction with other delivery devices or avenues. Likewise, the compositions described herein for abrasion of at least one biological tissue can be delivered to the at least one tissue by any means described herein. Some such means for delivery of the compositions described herein include, but are not limited to, ultrasound, iontophoresis (which involves applying an electrical potential across skin or other tissue in order to increase penetration of ionizable drugs), diffusion, electroporation, photomechanical waves (such as by producing pulses with Q-switched or mode-locked lasers to the skin or other tissue), needle-free injections, electro-osmosis, artificial vesicles, laser radiation, magnetophoresis (utilizing a diamagnetic substance for use with a magnetic field for increased penetration of the composition into the biological tissue), microscissuining, controlled heat aided delivery (which involves heating the skin prior to or during therapeutic administration), or tattoos and etchings.

Some non-limiting examples of particular diamagnetic substances include wood, water, organic compounds (such as petroleum), metals (including copper, mercury, gold, bismuth), or benzoic acid.

In one particular example, skin abrasion for superficial resurfacing (e.g., microdermabrasion) can be used to treat acne, scars, hyperpigmentation, and other skin blemishes, as described herein. Microscissuining creates microchannels in the skin by eroding the outer layers of skin with sharp microscopic metal granules (Carlisle Scientific, Carlisle, Mass.), and Med Pharm Ltd (Charlbury, UK) has developed a novel dermal abrasion device (D3S) for the delivery of difficult to formulate therapeutics ranging from hydrophilic low molecular weight compounds to other biopharmaceuticals, and can be utilized in conjunction with administration of at least one therapeutic composition described herein. (See e.g., Roberts, et al., Clin. Exp. Pharmacol. Physiol. vol. 24, pp. 874-9 (1997); Murthy, et al., J. Controlled Rel. vol. 93, pp. 49-57 (2003); each of which is incorporated herein by reference).

In at least one embodiment, Rathbone et al. have described artificial vesicles that mimic cell vesicles (such as TRANSFERSOMES®, from IDEA AG, Germany) can be utilized for administration of one or more therapeutic composition described herein. Artificial vesicles penetrate the skin barrier along the transcutaneous moisture gradient and causes “virtual” pores between the cells in an organ without affecting its biological properties. (See, e.g., Modified Release Drug Delivery Technology, N.Y., Marcel Dekker, Inc., vol. 126, pp. 471-619 (2004), which is incorporated herein by reference). In addition, liposomes, and niosomes also serve as carriers and can be utilized in administration of at least one therapeutic composition described herein.

In at least one embodiment, the one or more frozen particles are generated by spraying a jet or mist of the composition constituents into a low temperature environment (solid, liquid, gas, or any combination thereof) such that the compositions freeze and form frozen particles. In at least one embodiment, streams of frozen particles are extruded at low temperatures through fine ducts and into a low temperature environment. In at least one embodiment, the one or more frozen particles are propelled through a nozzle or other delivery apparatus. In at least one embodiment, the one or more frozen particles are delivered by utilizing flash boiling of a cold liquid. In one particular example, liquid nitrogen is flash boiled in order to accelerate, eject, or propel one or more frozen particles for delivery or administration to at least one cell, tissue, or subject. In at least one embodiment, the flash boiling is caused or enhanced by one or more laser pulses (e.g., an infrared laser pulse). In at least one embodiment, the one or more frozen particles are prepared, delivered, or administered by another means.

For embodiments described herein, those having skill in the art will recognize that the state of the art has progressed to the point where there is little distinction left between hardware, software, and/or firmware implementations of aspects of systems; the use of hardware, software, and/or firmware is generally (but not always, in that in certain contexts the choice between hardware and software can become significant) a design choice representing cost vs. efficiency tradeoffs. Those having skill in the art will appreciate that there are various vehicles by which processes and/or systems and/or other technologies described herein can be effected (e.g., hardware, software, and/or firmware), and that the preferred vehicle will vary with the context in which the processes and/or systems and/or other technologies are deployed. For example, if an implementer determines that speed and accuracy are paramount, the implementer may opt for a mainly hardware and/or firmware vehicle; alternatively, if flexibility is paramount, the implementer may opt for a mainly software implementation; or, yet again alternatively, the implementer may opt for some combination of hardware, software, and/or firmware. Hence, there are several possible vehicles by which the processes and/or devices and/or other technologies described herein may be effected, none of which is inherently superior to the other in that any vehicle to be utilized is a choice dependent upon the context in which the vehicle will be deployed and the specific concerns (e.g., speed, flexibility, or predictability) of the implementer, any of which may vary. Those skilled in the art will recognize that optical aspects of implementations will typically employ optically-oriented hardware, software, and or firmware.

In some implementations described herein, logic and similar implementations may include software or other control structures. Electronic circuitry, for example, may have one or more paths of electrical current constructed and arranged to implement various functions as described herein. In some implementations, one or more media may be configured to bear a device-detectable implementation when such media hold or transmit device detectable instructions operable to perform as described herein. In some variants, for example, implementations may include an update or modification of existing software or firmware, or of gate arrays or programmable hardware, such as by performing a reception of or a transmission of one or more instructions in relation to one or more operations described herein. Alternatively or additionally, in some variants, an implementation may include special-purpose hardware, software, firmware components, and/or general-purpose components executing or otherwise invoking special-purpose components. Specifications or other implementations may be transmitted by one or more instances of tangible transmission media as described herein, optionally by packet transmission or otherwise by passing through distributed media at various times.

Alternatively or additionally, implementations may include executing a special-purpose instruction sequence or invoking circuitry for enabling, triggering, coordinating, requesting, or otherwise causing one or more occurrences of virtually any functional operations described herein. In some variants, operational or other logical descriptions herein may be expressed as source code and compiled or otherwise invoked as an executable instruction sequence. In some contexts, for example, C++ or other code sequences can be compiled or implemented in high-level descriptor languages (e.g., a logic-synthesizable language, a hardware description language, a hardware design simulation, and/or other such similar mode(s) of expression). For example, some or all of the logical expression may be manifested as a Verilog-type hardware description or other circuitry model before physical implementation in hardware. Those skilled in the art will recognize how to obtain, configure, and optimize suitable transmission or computational elements, material supplies, actuators, or other structures in light of these teachings.

EXAMPLES Example 1 Compositions and Methods of Making Frozen Particles

Frozen particles suitable for various embodiments described herein may be produced by controlling the pressure and temperature of hydrogen oxide that is introduced as a liquid, gas or frozen. Frozen particles, including frozen hydrogen oxide ice Ic, are produced by cooling small hydrogen oxide droplets (˜6 μm diameter) below −38° C. (See e.g., Murray, et al., Phys. Chem. Chem. Phys. vol. 8, pp. 186-192 (2006), which is incorporated herein by reference). Emulsions of 30-40% by weight of distilled and de-ionized hydrogen oxide in paraffin oil (Fisher Scientific) are agitated to produce hydrogen oxide droplets of mean diameters ranging from 5 to 35 μm as determined by optical microscopy. The droplets are cooled to −100° C. at a rate of 10° C./min by using a cryostat cooled with liquid nitrogen and containing a heater and temperature controller. Freezing liquid droplets with a median diameter of 5.6 μm or smaller can provide approximately 80% frozen ice Ic and approximately 20% frozen ice Ih. Following the procedures of Murray et al, selective production of ice Ic in pellet form produces quantities suitable for use in various embodiments described herein.

Frozen particles generated in this manner are utilized for abrasion of at least one biological tissue, including but not limited to skin. The frozen particle composition is administered to at least one biological tissue by, for example, accelerating, ejecting, or propelling the frozen particles by way of a carrier gas under pressure (e.g., air, carbon dioxide, nitrogen) through a tube, or other device directed toward at least one biological tissue, such as skin. Microdermabrasion, microscissuining, or other surface abrasion techniques are carried out in a similar fashion.

Example 2 Compositions and Methods of Making Frozen Particles

Frozen particles, including frozen hydrogen oxide ice Ic, are produced by depositing hydrogen oxide vapor onto a copper plate held at low temperatures in vacuo. Purified (deionized) hydrogen oxide is added to a vessel at approximately 25° C. and the hydrogen oxide vapor is condensed onto a metal plate held at approximately −196° C. in vacuo. The deposited amorphous ice is heated (at 10° C./min) to approximately −93° C. and is converted to crystalline cubic ice (ice Ic). Ice Ic is stable when stored under liquid nitrogen (See e.g., Johari, et al., J. Phys. Chem., vol. 94, pp. 1212-1214 (1990), which is incorporated herein by reference). An example of an apparatus that is used to produce frozen hydrogen oxide ice Ic is described in Hallbrucker et al (J. Phys. Chem., vol. 93, pp. 4986-4990 (1989), which is incorporated herein by reference).

Example 3 Compositions and Methods of Making Frozen Particles

Frozen hydrogen oxide ice Ic particles are produced from small hydrogen oxide droplets in an example of a “pelletizer” apparatus similar to those described by, for example, U.S. Pat. No. 4,617,064; U.S. Pat. No. 6,306,119, which are incorporated herein by reference. Frozen hydrogen oxide ice Ic particles are formed by spraying hydrogen oxide droplets of the desired size into a cooling chamber filled with a cold inert gas maintained at the desired temperature, for example, nitrogen gas maintained at approximately −100° C. to promote formation of ice Ic. Spray droplet size is maintained by variation of nozzle/orifice size and hydrogen oxide pressure to yield droplet diameters ranging from nanometers to centimeters. Frozen hydrogen oxide ice Ic, ice Ih, amorphous low density ice, amorphous high density ice, and other forms are produced by controlling the temperature and pressure of the cooling chamber. Cubic hydrogen oxide ice Ic particles are formed in a step-wise process, by maintaining the chamber at a very low temperature (approximately −196° C.) with increased pressure, which first promotes formation of amorphous hydrogen oxide ice. Next, the chamber is heated to approximately −93° C., which results in transformation to cubic hydrogen oxide ice (ice Ic) particles.

The hydrogen oxide ice particles are propelled into a delivery system (such as tubing and nozzle) by nitrogen gas under pressure. The delivery system is maintained at the appropriate temperature for preservation of the hydrogen oxide particle structure, (e.g., approximately −93° C. for ice Ic structure).

Example 4 Compositions and Methods of Making Frozen Carbon Dioxide Particles

Carbon dioxide frozen particles are produced from small carbon dioxide droplets in a “pelletizer” similar to those described by, for example, U.S. Pat. No. 4,617,064; and U.S. Pat. No. 6,306,119; each of which is incorporated herein by reference. Carbon dioxide frozen particles are formed by spraying liquid carbon dioxide droplets into a cooling chamber maintained at low temperatures (e.g., approximately −100° C.). Droplet size is regulated by varying nozzle or orifice size, and pressure. Carbon dioxide droplet diameters range, for example, from nanometers to centimeters. The frozen carbon dioxide particles are propelled into a delivery system (e.g., tubing and nozzle) by carrier gas, (e.g., air or nitrogen) under pressure. The carbon dioxide particles are maintained while in the delivery system at the appropriate temperature, (e.g., approximately −100° C.). Frozen carbon dioxide particles sublimate, or transition to a gas phase, at approximately −78.5° C. and 1 atm pressure.

Example 5 Compositions and Methods of Making Frozen DMSO Particles

Dimethyl sulfoxide (DMSO) frozen particles are produced from DMSO droplets, for example, in a “pelletizer” apparatus similar to those described by, for example, U.S. Pat. No. 4,617,064; U.S. Pat. No. 6,306,119, which are incorporated herein by reference. DMSO frozen particles are formed from spraying liquid DMSO droplets of the desired size into a cooling chamber that is maintained at low temperature, for example, less than approximately 18.5° C. Droplet size is regulated by varying nozzle or orifice size, and pressure, with compressed air as a carrier gas. Droplet size can be regulated by varying nozzle or orifice size, and DMSO pressure. DMSO droplet diameters range, for example, from nanometers to centimeters. The DMSO frozen particles are propelled by a carrier gas (e.g., air or nitrogen) under pressure to enter a delivery system (e.g., tubing and nozzle). In order to preserve DMSO particle structure, the delivery system is maintained at low temperature (e.g., less than approximately 18.5° C.).

Example 6 Methods of Assessment or Selection of Frozen Particles

According to various embodiments described herein, at least one frozen particle is made by lowering the temperature of liquid droplets of a selected material. Droplet and particle sizes are measured by imaging a spray or particle stream upon a background screen. The background screen is illuminated with a short pulse of light, for example, from an infrared laser beam (at approximately 805 nm), which is capable of pulsing at frequencies of approximately 1000 Hz. A digital camera captures high resolution images of the droplets or particles.

High-speed, real-time particle sizing software analyses the images to assess the diameter distribution for the particles and to determine the shape. The diameter of each droplet is determined automatically by referencing the number of dark pixels in the droplet image to the pixel area of a calibration circle. Droplet diameters between approximately 100 μm (±3.2%) and approximately 2000 μm (±0.03%) were measured with 95% confidence (See e.g., Ireland et al., 6th ASME-JSME Thermal Engineering Joint Conference (2003), which is incorporated herein by reference). Instruments, computer programs and protocols for measuring particle and droplet size are available, for example, from Oxford Lasers, Shirley, Mass. (e.g., world wide web at oxfordlasers.com, which is incorporated herein by reference).

Example 7 Methods of Assessment or Selection of Frozen Particles

According to various embodiments described herein, at least one frozen particle is made by lowering the temperature of liquid droplets of a selected material. Droplet and particle sizes are measured by laser diffraction. Laser diffraction based particle size analysis relies on particles passing through a laser beam and scattering light at an angle that is directly related to their size. As particle size decreases, the observed scattering angle increases logarithmically. Scattering intensity is also dependent on particle size, and decreases with decreasing particle volume. Thus, large particles scatter light at narrow angles with high intensity whereas small particles scatter at wider angles but with low intensity. Laser diffraction is used for the non-destructive analysis of wet or dry samples, to measure particles in the size range 0.02 to 2000 micrometers (e.g., world wide web at chemie.de/articles/e/61205/, which is incorporated herein by reference). A laser diffraction instrument, protocols and analysis software are available, for example, from Malvern Instruments Ltd. (Malvern, Worcestershire, WR14 1XZ United Kingdom).

Example 8 Compositions and Methods of Making Frozen Particles Including a Reinforcement Agent

One or more reinforcement agents are added to the frozen particles during the formation process. Among other things, reinforcement agents can increase the strength of frozen particles (e.g., increase the modulus of rupture of ice) and decrease the deformation of frozen particles (e.g., decrease the beam deflection of ice). As indicated in Table A below, glass fibers present at 9% (wt./vol.), for example, increase the modulus of rupture of ice by approximately 7-fold relative to ice derived from unreinforced hydrogen oxide ice (See e.g., Kingery, Science, vol. 134, pp. 164-168 (1960), which is incorporated herein by reference).

TABLE A Strength of fresh ice with sawdust and Fiberglass, respectively, added. Additions were % wt./vol. (Kingery, Ibid). Modulus of rupture (kg/cm²) Addition (%) Sawdust (−17° C.) Fiberglass (−20° C.) 0 22.5 24.1 0.8 22.7 24.0 2.5 35 65.4 9.0 60 161 14.0 66.7 N/A

As indicated in FIG. 5, the beam deflection is less than 0.005 inches for hydrogen oxide ice that is reinforced with approximately 9.0% glass fibers and increases over time for hydrogen oxide ice that is reinforced with approximately 0.8% glass fibers (Kingery, Ibid). Furthermore, hydrogen oxide ice with approximately 9% (w/v) of glass fibers is not deformed over 23 hours under an applied force of approximately 24.5 in.lbs. As described in Kingery, et al, and as indicated in FIG. 5, beam deflection of hydrogen oxide ice with approximately 0.8% glass fibers is approximately 0.16 inches after 23 hours under 25.3 in.lbs. of force. Likewise, as indicated in FIG. 5, and according to Kingery et al, hydrogen oxide ice without reinforcement agents is deformed approximately 0.05 inches after 4 hours under approximately 26.6 in.lbs. of force. Additionally, aluminum and silica carbonate particles can be mixed at various volume fractions and co-milled under an argon atmosphere to produce nanocrystalline composites as reinforcement agents for frozen particle compositions. (See e.g., Kamrani, et al., Powder Met. vol. 50, pp. 276-282(7) (2007), which is incorporated herein by reference).

Example 9 Compositions and Methods of Making Frozen Particles

Frozen particles (e.g., carbon dioxide, DMSO, gelatin) are reinforced by incorporating one or more reinforcement agents, including but not limited to silica beads, fiberglass, polyethylene glycol, kaolin, or wood fibers.

Silica beads approximately 1 micrometer in diameter are mixed with hydrogen oxide at approximately 0° C. to make volume fractions including the approximate ranges, but not limited to, 0, 0.004, 0.04, 0.15, 0.29, 0.49 and 0.63 volume fraction.

The volume fractions, or one or more particular volume fraction, are frozen in, for example, a cylindrical mold, at low temperatures (e.g., approximately −10° C.). Unconfined coaxial compression tests are used to determine the maximum stress (also known as the failure point) of the one or more frozen particles at defined temperatures and strain rates (See e.g., Yasui et al, Geophys. Res. Lett., vol. 35, L12206, (2008), which is incorporated herein by reference).

As indicated in FIG. 6, maximum stress values (MPa) increase for mixtures with an increased volume fraction of silica beads relative to the maximum stress for unreinforced hydrogen oxide ice. (See e.g., Yasui et al, Ibid.) φ=silica volume fraction

The strength of specific frozen particles is altered by varying the composition of frozen particle mixtures containing one or more reinforcement agents. For example, Table B indicates the frozen particle strength of frozen particles including hydrogen oxide, DMSO, carbon dioxide, and gelatin, which contain at least one reinforcement agent. As indicated, the reinforced frozen particles exhibited increased strength compared to their unreinforced counterparts. As indicated in Table B, frozen particles containing at least one reinforcement agent at the volume fractions shown in the table displayed maximal strength in compression tests. (See also, FIGS. 5 and 6, as well as Table A herein for hydrogen oxide frozen particle strength).

Example 10 Vaccine Compositions and Methods of Making Frozen Particles

As described herein, immunization of a subject with a vaccine is accomplished by way of introduction of the vaccine through, for example, subcutaneous, transcutaneous or intramuscular administration. (See e.g., Berzofsky et al, Nat. Rev. Immunol. vol. 1, pp. 209-219, (2001), which is incorporated herein by reference). Non-limiting examples of frozen particle vaccines are described herein, and include one or more immunogens. The immunogen therapeutic compositions are made, for example, in solution or as a solid in suspension created from buffered solutions (e.g., phosphate, citrate, lactate, pyruvate or an organic acid buffer) that optimize the stability and immunogenicity of the vaccine.

Storage stability of vaccines depends upon many factors, including vaccine formulation and storage temperature. For example, an influenza subunit vaccine formulated with trehalose, and Hepes buffered saline, is stable at room temperature for approximately 26 weeks (See e.g., Amorij et al, Pharm. Res. vol. 25, pp. 1256-1273 (2008), which is incorporated herein by reference).

Vaccines with adjuvants such as: N-acetyl muramyl-1-alanyl-d-isoglutamine, also called muramyl dipeptide (MDP) or monophosphoryl lipid A (MPL) elicit enhanced cellular and humoral immunity (See e.g., Aguilar et al Vaccine vol. 25, pp. 3752-62 (2007), which is incorporated herein by reference).

One or more hydrogen oxide frozen particle vaccine compositions, including, for example, one or more buffers, one or more immunogens (e.g., viral protein subunits) and one or more adjuvants, as a solution or suspension, are made by spraying the compositions through an orifice or nozzle. Each vaccine composition is propelled by a pressurized gas (e.g., compressed air) into a cooling chamber maintained at, for example, approximately −40° C.

The vaccine composition is delivered to at least one biological tissue of a subject, for example, by propelling the particles via a carrier gas under pressure (e.g., air, carbon dioxide, nitrogen) through a tube directed toward at least one biological tissue (including but not limited to vascular, lymphatic, lymph node, epidermal, subcutaneous, intramuscular, oral, nasal, pulmonary, intraperitoneal or rectal tissue).

Alternatively, the vaccine composition is delivered to at least one biological tissue of a subject, for example, by first forming the frozen particle vaccine compositions through spraying composition droplets into a cryogen bath (e.g., liquid nitrogen). The frozen particle compositions are subsequently delivered to at least one biological tissue by flash boiling liquid nitrogen, and propelling the frozen particle compositions through a tube or barrel, for example, to at least one biological tissue of a subject.

Frozen particle vaccine compositions containing one or more reinforcement agents (e.g., silica beads) and of the appropriate size and shape (e.g., bullet, spheroid, high aspect ratio shape) penetrate the at least one biological tissue when propelled to high velocity by a carrier gas. In one non-limiting example, a vaccine composition approximately 20-70 nm in size penetrates the epidermis when the composition is accelerated to high speed with a powder jet injector (PowerJect, PowerJect Pharmaceuticals) (Amorij et al, Ibid.).

Example 11 Vaccine Compositions and Methods of Making Frozen Particles

Frozen particle vaccine compositions containing multiple immunogens, for example, toxoids (chemically modified toxins) from bacteria such as Clostridium tetani, Cornybacterium diphtheriae or Bordetella pertussis, stimulate immunity to multiple bacteria or toxins in a single vaccine composition.

Alternatively, multiple distinct immunogens, proteins, or peptides that are derived from a single pathogen are combined in a single frozen particle vaccine composition that immunizes a subject against a pathogenic virus or bacteria that mutates frequently. For example, multiple hemagglutinin or neuraminidase proteins, (e.g., H1N1, H3N2) from different viral strains (e.g., A/New Calcdonia/H1N1, or A/Wellington/H3N2) or viral species of influenza (e.g., influenza A or influenza B) are combined in a single frozen particle vaccine composition and provides immunity to multiple strains or species. (See e.g., Kamps et al, Influenza Report, pp. 127-149 (2006); world wide web at influenzareport.com/ir/vaccines; each of which is incorporated herein by reference).

Alternatively, frozen particle vaccine compositions including one or more immunogens, antigens or proteins (e.g., influenza A/New Caledonia/(H1N1)) are combined with one or more frozen particle vaccine compositions containing one or more different antigens (e.g., influenza B/Shanghai or influenza A/Wellington/(H3N2)). Such a frozen particle vaccine composition combination provides immunity against seasonal variants of viral pathogens.

In one non-limiting example, combinations of frozen particle vaccine compositions including specific antigens from selected influenza variants or strains target a seasonal flu epidemic. (Kamps et al, Ibid.) Combination of frozen particle compositions are made containing one or more different antigens or epitopes, wherein the one or more different antigens or epitopes are derived from mutant or variant HIV proteins that evolve during HIV infection (See e.g., Berzofsky et al, J. Clin. Inv. vol. 114, pp. 450-462 (2004)). Such combination compositions immunize a subject against existing HIV mutants and anticipate the emergence of new HIV mutants or variants.

Alternatively, one or more frozen particle vaccine compositions are delivered to one or more mucosal tissues (e.g., nasal, oral, rectal, pulmonary) via propulsion using a “pellet gun,” via inhalation, or ingestion by a subject. For example, an influenza vaccine lyophilized and delivered nasally as spherical particles, approximately 26.9 μm (mean diameter), induces mucosal (e.g., nasal IgA response) and systemic immunity (e.g., serum antibody response) to influenza virus (See e.g., Garmise et al, AAPS PharmSciTech. vol. 8:E81 (2007); Huang et al, Vaccine. vol. 23(6), pp. 794-801 (2004); each of which is incorporated herein by reference).

Alternatively, the one or more frozen particle vaccine compositions are delivered to one or more pulmonary surfaces of the subject via propulsion by way of a “pellet gun,” by using flash boiled liquid nitrogen as a propellant, or by inhalation. Frozen particle influenza vaccine compositions administered to one or more pulmonary surfaces of a subject elicit mucosal and systemic humoral, as well as cell-mediated immune responses to influenza (See e.g., Amorij et al Vaccine. vol. 25, pp. 8707-8717 (2007), which is incorporated herein by reference).

Example 12 Compositions and Methods of Making Frozen Particles

Frozen particle compositions of the appropriate size and shape, including botulinum toxin, an optimal buffer (e.g., Hepes buffer), one or more stabilizing agents, and one or more reinforcement agents are administered through the skin of a subject to neuromuscular junctions. Botulinum toxin inhibits acetylcholine release, which blocks synapse formation, and temporarily paralyzes the corresponding musculature.

Frozen particle compositions containing a recommended dose of botulinum toxin (See e.g., Borodic, U.S. Pat. No. 5,183,462, which is incorporated herein by reference), and at least one reinforcement agent (e.g., polymer) are administered to skeletal muscles using a delivery system derived from inkjet printer technology (See e.g., world wide web at en.wikipedia.org/wiki/Inkjet Printer) that sprays picoliter quantities of the frozen particle compositions at high velocity (e.g., 50 msec) toward the skin of the subject. Botulinum toxin is typically administered by subcutaneous injection (generally with a 26 gauge hypodermic needle). Botulinum toxin is approved by the FDA for therapy of strabismus (crossed-eyes), blepharospasm (uncontrolled blinking), and other facial nerve disorders including hemifacial spasm. It is also approved for treatment of cervical dystonia and glabellar (frown) lines (See e.g., Jankovic, J. Neurol. Neurosurg. Psychiatry vol. 75, pp. 951-957 (2004), which is incorporated herein by reference).

In addition, botulinum toxin is included in the treatment of focal or segmental dystonia (e.g., oromandibular-facial-lingual dystonia, laryngeal dystonia, limb dystonia). Dystonias are neurological disorders with repetitive and patterned contractions of muscles that cause abnormal movements and postures. For example, cervical dystonia subjects are injected with, for example, approximately 100 I.U of botulinum toxin, distributed over 3-5 injection sites, spaced 5-15 mm apart, across the length of the sternomastoid muscle. (Borodic, Ibid.)

Frozen particle vaccine compositions containing botulinum toxin are administered to facial muscles that underlie frown lines, wrinkles, and “crow's feet.” For example, botulinum toxin is targeted to: 1) the corrugator and procerus muscles to treat vertical glabellar eyebrow furrows; 2) to multiple sites in the frontalis muscle to eliminate horizontal lines in the forehead; or 3) to the lateral orbicularis oculi to treat crow's feet.

Frozen particle compositions containing an optimal dose of botulinum toxin (e.g., 0.2-0.4 I.U./kg) are administered over the length of a specific facial muscle (e.g., orbicularis oculi) by use of a delivery system with an inkjet nozzle. As described herein, picoliter volumes of one or more frozen particle compositions are sprayed at a velocity that achieves a desired or predetermined depth (for example, 5-8 mm; Borodic, Ibid.). The velocity is also altered according to the size, shape, and constituents of the frozen particle composition.

Example 13 Methods of Administering Frozen Particle Therapeutic Compositions

Frozen hydrogen oxide particles of ice Ic form and at least one therapeutic agent or at least one diagnostic agent are formulated for treatment of hematological cancers (e.g., leukemia or lymphoma) or solid tumors (e.g., carcinoma, sarcoma). For example, at least one of neo-adjuvant therapy, adjuvant therapy, chemotherapy, antibody therapy, or immunotherapy are employed

In one non-limiting embodiment, frozen hydrogen oxide particles are used for adjuvant therapy of cancers treated with surgery such as colon cancer, lung cancer, and breast cancer. At least one frozen particle hydrogen oxide therapeutic composition containing one or more reinforcement agents (e.g., silica beads, Kevlar®), one or more buffers, one or more stabilizing agents (e.g., one or more saccharides), and one or more cancer therapeutic agents (such as one or more chemotherapy drugs, antibodies, biological agents (e.g., antibodies, cytokines or peptides), or one or more chemotherapeutic agents) are administered to an area proximal to a region of at least one biological tissue where a tumor is present or believed to be present. Optionally, resection of at least a part of a tumor may be performed, with or without additional administration of the at least one frozen particle therapeutic composition.

The at least one frozen particle therapeutic composition is administered in such a manner as described herein, that allows for desired depth of penetration of the at least one biological tissue. In one embodiment, the at least one frozen particle therapeutic composition is administered to a depth that allows for at least one of intracellular or intercellular delivery. For example, the at least one frozen particle therapeutic composition is administered to a depth that allows for delivery to at least one of epithelium, endothelium, vasculature, lymphatic vessels, lymph nodes or mucosa.

Specifically, if metastasis is present or believed to be present in the subject, administration of the at least one frozen particle therapeutic composition is delivered to such region of metastases or micro-metastases are believed to be present.

Frozen particle hydrogen oxide therapeutic compositions provide as an adjuvant therapy are administered by spraying at least one composition under pressure with a carrier gas through a nozzle designed to uniformly distribute particles over at least one biological tissue at sufficient velocity to penetrate the tissue exposed during tumor resection.

Advanced colon cancer (e.g., stage II, III) is treated surgically by removal of sections of colon containing tumor with margins of “normal” colon tissue and often includes removal of associated lymph nodes and mesentery (colectomy). Standard adjuvant therapy following surgery is systemic administration of a combination of chemotherapy drugs (e.g., 5-fluorouracil, leucovorin or oxaliplatin (FOLFOX)), (See e.g., Wolpin et al, CA Cancer J. Clin. vol. 57, pp. 168-185 (2007)). Systemic FOLFOX adjuvant therapy is associated with significant toxicities including gastrointestinal toxicity, neutropenia and neurotoxicity (Wolpin et al, Ibid.). Localized in situ delivery of FOLFOX by administration of frozen particle therapeutic compositions permits delivery of a lower dose.

Administration of at least one frozen particle hydrogen oxide therapeutic composition containing at least one therapeutic antibody includes, for example, bevacizumab (an anti-vascular endothelial growth factor) or cetuximab (an anti-epidermal growth factor receptor). Bevacizumab and cetuximab both target the tumor-associated vasculature and tumor cells in the remaining colon sections and the surrounding tissues, mesentery and lymph nodes. Localized administration of therapeutic antibodies provides sustained protection from recurrence of colon tumors at the site of tumor resection and in the surrounding tissues. (Wolpin et al, Ibid.). Following surgery and adjuvant therapy with one or more frozen particle hydrogen oxide therapeutic compositions, including at least one of one or more chemotherapy drugs, or one or more antibodies, the remaining colon sections are spliced together (i.e. anastomosis) or an artificial orifice (i.e. stoma) is inserted to restore a functional colon.

Example 14 Methods of Administering Frozen Particle Therapeutic Compositions

Frozen particle hydrogen oxide therapeutic compositions including one or more cancer therapeutics or one or more cancer diagnostics are used to treat cancers in distal locations from the primary tumor or initial tumor site treated with surgery or radiation. For example, colon cancer cells often metastasize to the liver ((Wolpin et al, Ibid.). At the time of surgical resection of colon cancer tumors, one or more frozen particle hydrogen oxide therapeutic compositions including at least one cancer therapeutic, such as one or more cytotoxic drugs (e.g., fluouracil), antibodies (e.g., cetuximab), radioisotopes conjugated to antibodies (e.g., ¹³¹1-cetuximab), or one or more mixtures of at least one cytotoxic drug and at least one biological-based therapeutic agent are administered to the liver and surrounding tissues. Administration of the at least one frozen particle hydrogen oxide therapeutic composition is accomplished by traditional surgery or laparoscopic surgery that allows access to the liver (or other organs to be treated). Administration of at least one frozen particle hydrogen oxide therapeutic composition directly to the liver and the surrounding vasculature allows for intracellular or intercellular penetration and release of at least one anti-cancer therapeutic for treatment of any existing or suspected colon cancer mestastases or micro-metastases.

As described herein, the at least one frozen particle hydrogen oxide therapeutic composition including one or more cancer therapeutics are administered by way of a spraying device. Such a spraying device includes an insulated tube and nozzle, as well as a valve that controls the flow of particles. In the case of traditional surgery for tumor or tissue resection, the at least one frozen particle hydrogen oxide therapeutic composition is sprayed directly onto the target tissue or tissues. Whereas in the case of laparoscopic surgery for tumor or tissue resection, the at least one frozen particle hydrogen oxide therapeutic composition is sprayed through a trocar (a hollow tube approximately 10 millimeters in diameter).

In certain spraying devices, the at least one frozen particle hydrogen oxide therapeutic composition is administered by way of a carrier gas. The depth of penetration by the at least one therapeutic composition is controlled by regulating the carrier gas pressure as well as the consequent particle velocity. The at least one therapeutic composition optionally includes one or more tracer agents or is delivered simultaneously with one or more tracer agents. Some non-limiting examples of tracer agents include dyes, stains or fluorescent compounds that mark the tissue area sprayed. The one or more tracer agents can optionally monitor or provide feedback as to the quantity or quality (in the case of multiple therapeutic compositions administered simultaneously or over time) of the at least one therapeutic composition administered to a specific site.

In at least one embodiment, the at least one frozen particle hydrogen oxide therapeutic composition including at least one cancer therapeutic further includes hematoxylin and eosin stains mixed at a known ratio (e.g., 1:10). Alternatively, a batch of the at least one frozen particle hydrogen oxide therapeutic composition is administered in a mixture or in separate applications frozen particles including hematoxylin and eosin stains. Staining of tissues is visualized by inspection with a low power microscope (e.g., dissection microscope) or with a laparoscope, which allows for assessment of the relative quantity or quality of the at least one therapeutic composition administered to the tissue. Staining of the tissues further provides a guide as to the region that received the at least one therapeutic composition.

Example 15 Methods of Administering Frozen Particle Therapeutic Compositions

Frozen particle hydrogen oxide therapeutic compositions including carbon dioxide and at least one cancer therapeutic are administered to at least one tumor or tissue suspected of being cancerous. Upon administration, the frozen particle hydrogen oxide therapeutic compositions penetrate one or more tumor cells, warm to ambient temperature, and undergo rapid sublimation and gaseous expansion of the carbon dioxide. This rapid reaction produces a small explosion that destroys at least one tumor cell as well as one or more adjacent cells. In addition, administration of the frozen particle therapeutic compositions at low temperatures (e.g., lower than approximately −78.5° C., which is the approximate sublimation temperature for carbon dioxide at 1 atm pressure), freezes cells and tissues, causing tumor cell death (See e.g., Vergnon et al, Eur. Respir. J. vol. 28 pp. 200-218 (2006); incorporated herein by reference).

Alternatively, carbon dioxide gas is entrapped in frozen particles by placing the liquid phase (e.g., hydrogen oxide) under high pressure in the presence of carbon dioxide gas. (See e.g., U.S. Pat. Nos. 4,289,794; 4,289,790; 4,262,029; 5,439,698, each of which is incorporated herein by reference). Administration of the at least one therapeutic composition is conducted as described herein. In at least one embodiment, the use of a tube and nozzle is used that sprays the frozen particle therapeutic compositions under pressure in a carrier gas (e.g., carbon dioxide, nitrogen). Administration of the at least one therapeutic composition is carried out as an adjuvant therapy in conjunction with tumor resection, or as an alternative when tumor resection is not favored. For example lung cancer tumors are generally inoperable when such tumors are adjacent to airways, or infiltrate central airways including the trachea, main stem bronchi or multiple lung lobes. Additionally, subjects with compromised respiration (e.g., those with lung disease, heart disease or advanced age) are generally not candidates for surgery (See e.g., Spiro et al, Amer. J. Respir. Crit. Care Med., vol. 172, pp. 523-529 (2005); which is incorporated herein by reference).

Carbon dioxide frozen particle therapeutic compositions including one or more chemotherapeutic drugs (e.g., cisplatin, docetaxel, vinorelbine), targeted drugs (e.g., gefitnib, erlotnib), or biological-based agents (e.g., cetuximab, panitumumab, bevacizumab) are administered directly onto lung cancer tumors. Administration is conducted via endoluminal bronchoscopy or by video-assisted thoracoscopy by means of an insulated tube and nozzle integral to the endoscopic device. Frozen particle composition velocities and spray rate are controlled by a valve between the spray head and the cooling chamber of the “pelletizer.” (See e.g., U.S. Pat. No. 6,306,119, or 6,764,493, each of which is incorporated herein by reference). Precise localization and administration of the frozen particle therapeutic compositions are accomplished by bronchoscopy and endoscopy with fluoroscopy used to mark the field(s) of interest.

Methods for endoscopic targeting of tumors are described, for example, in Huber et al (Chest vol. 107, pp. 463-470 (1995); which is incorporated herein by reference). Moreover, computed tomography, magnetic resonance imaging, positron emission tomography or other techniques are used to locate lung cancer tumors.

Frozen particle therapeutic composition administration by using endoscopic procedures or as an adjuvant therapy in conjunction with traditional surgery is used for various regions of existing or potential carcinogenesis, including mediastinal lymph nodes, vasculature, chest wall and other thoracic sites.

Alternatively, frozen particle therapeutic compositions are delivered during traditional surgery for lung cancer and used to treat inoperable tumors remaining following lobectomy, wedge resection, and pneumonectomy, as well as to treat margins of lobe, wedge or lung excisions to reduce recurrence of lung cancer (See e.g., the worldwideweb at en.wikipedia.org/wiki/Lung_cancer#Surgery; which is incorporated herein by reference). Without wishing to be bound by any particular theory, frozen particle carbon dioxide therapeutic compositions maintained at approximately −80° C. while administered to tumors rapidly freeze the tumor cells leading to formation of ice crystals in tumor cells that destroy cell organelles (e.g., mitochondria) leading to death of the tumor cells. (Vergnon et al, Ibid.)

Similarly, frozen particle therapeutic compositions containing at least one radioactive element deliver radiation to lung cancer tumor cells. One non-limiting example utilizes frozen particle therapeutic compositions including ¹⁹²Iridium for irradiating lung tumors that obstruct major airways. Administration of the frozen particle therapeutic compositions is conducted using an endoscope and a wire to place the radioactive compositions in at least one lung tumor. Without wishing to be bound to any theory, tumor cell irradiation results in single-stranded DNA breaks that induce apoptosis and reduce rates of cell division (Vergnon et, Ibid.).

While particular aspects of the present subject matter described herein have been shown and described, it will be apparent to those skilled in the art that, based upon the teachings herein, changes and modifications may be made without departing from the subject matter described herein and its broader aspects and, therefore, the appended claims are to encompass within their scope all such changes and modifications as are within the true spirit and scope of the subject matter described herein. It will be understood by those within the art that, in general, terms used herein, and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as “open” terms (e.g., the term “including” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes but is not limited to,” etc.). It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to claims containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” and/or “an” should typically be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, typically means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). In those instances where a convention analogous to “at least one of A, B, or C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, or C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). It will be further understood by those within the art that typically a disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms unless context dictates otherwise. For example, the phrase “A or B” will be typically understood to include the possibilities of “A” or “B” or “A and B.”

With respect to the appended claims, those skilled in the art will appreciate that recited operations therein may generally be performed in any order. Also, although various operational flows are presented in a sequence(s), it should be understood that the various operations may be performed in other orders than those which are illustrated, or may be performed concurrently. Examples of such alternate orderings may include overlapping, interleaved, interrupted, reordered, incremental, preparatory, supplemental, simultaneous, reverse, or other variant orderings, unless context dictates otherwise. Furthermore, terms like “responsive to,” “related to,” or other past-tense adjectives are generally not intended to exclude such variants, unless context dictates otherwise.

All publications and patent applications cited in this specification are incorporated herein by reference to the extent not inconsistent with the description herein and for all purposes as if each individual publication or patent application were specifically and individually indicated to be incorporated by reference for all purposes.
